595,059. Divided and this application December 5, 1933, Serial No.700,966. Renewed March 6 Claims.

This is a division of my application Serial No. 595,059, filed February25, 1932.

This invention relates to the supporting and manipulating of the runningand fresh web rolls and of the running web for the purpose of splicingthe running web to the fresh roll.

The principal objects of the invention are to provide for supporting therolls in a position so that there will be no necessity for slowing downthe press when the splicing is to take place, and to provide means bywhich the loading of the new rolls is facilitated and the floor spacedemanded for rotating the rolls and supporting them while the splice ismade will be reduced to a minimum, so that each roll supporting devicecan be placed within the over-all dimensions of a single unit of themodern type unit press.

Other objects and advantages of the invention will appear hereinafter.

Reference to be had to the accompanying drawing, in which Fig. 1 is anend view of a roll supporting and. loading device constituting apreferred embodiment of the invention;

Fig. 2 is an elevation of the same;

Fig. 3 is an end view partially diagrammatic with the rolls in theposition they assume just prior to splicing, and

Fig. 4 is an end view indicating the path of the roll.

This invention relates particularly to the manner in which the rolls andweb are manipulated and supported before and after splicing.

The running roll R and the fresh roll R are carried by a pair ofpedestals I secured to the floor of the building so as to provide astrong and rigid mounting for the rolls.

A construction is shown arranged to take up less space than usual inwhich the pedestals provide a mounting for two shafts 45 which arearranged in axial alignment, each of which has at one end a gear 46driven by a worm 41 for the rotation of these shafts. It is intendedthat the shafts, after proper adjustment, shall rotate simultaneously.Each shaft 45 carries a spider 48 secured to it. These parts constitutea reel The arms of the spiders at their outer ends provide rotatablemountings for shafts 49. On one end of each shaft 49 is a gear 50, and.on the other end a crank arm 5|, the free end of which carries arotatable chuck 52. These chucks provide mountings for the paper rolls.

The gears 50 mesh with larger gears 53, each of which is secured instationary position to its pedestal. When the shafts 45 are rotated bythe worm wheels, the spiders of course rotate. However, on account ofthe meshing of the gears 50 with the stationary gears 53 at each end,the crank arms on the shafts 49 describe a circular spiral path.

In rotating a reel of this type the outside periphery of a full rolldoes not necessitate as much lateral space as is needed when a simplerotary .fixed arm reel is used. This feature is particularly useful atthe present time due to a trend toward a printing press unit built insmall lateral dimensions. It has all of the essential features of arotary reel that are needed for running and. splicing and is aconsiderable space saver. As will be seen in Fig. 4, the path of theroll is of oblong shape, considerably longer than it is wide. So spaceis saved at each side.

By reference to Fig. 3, it will be seen that when the running roll R,supported by one of the pairs of crank arms 5| is of small diameter itis possible to load the new roll R and pass it up from the loadingposition to the spare roll position which is above that of the expiringone. Fig. 3 shows the running roll R just before exhaustion with theincoming roll B being rotated up to web speed by the normally inactivepress-driven means 21. This belt is driven by pulleys and a belt 28 froma shaft 26. This shaft is located on the printing press and operatedthereby in proportion to the speed of the press. At the proper time thesplice is made through the action of the brush 29.

It will be seen that the fresh roll R can be rotated up to Web speed bya normally inactive means 21, preferably operated from a shaft of thepress at such a speed that the belts of which it is composed will run atthe speed of the web being drawn into the press. It will also be seenthat a comparatively small floor space is required, reducing the demandfor room which is very great, as high speed presses are used only in thelargest cities where floor space is at a premium.

Having thus described my invention and the advantages thereof, I do notwish to be limited to the details herein disclosed, otherwise than asset forth in the claims, but what I claim is:-

1. In asupport for web rolls, the combination of a reel adapted to turnon an axis, means on the reel for supporting a Web roll, and means forswinging the web roll about an axis at a distance from the axis of thereel and rotatable therewith as the reel rotates, for the purposedescribed.

2. In a support for web rolls, the combination with a reel adapted toturn on an axis, of shafts carried by the reel, crank arms on saidshafts having eccentric chucks for supporting the web rolls, and meansfor turning said crank arms on their axes when the reel is turned on itsaxis, for the purpose described.

3. In a support for web rolls, the combination of a rotatable supportingframe, means thereon for carrying the web rolls, and means whereby therotation of said frame on its own axis will bodily move the web rollsthereon relatively to the frame in an oblong path longer vertically thanhorizontally.

4. In a web splicing device, the combination of a pair of shafts inaxial alignment, each having a spider thereon, said spiders beingprovided at the ends of their arms with chucks for supporting web rolls,means for rotating said shafts to bring the web rolls to the desiredposition, normally inactive but press-driven means for rotating a freshweb roll on said spiders up to web speed, and means whereby when saidshafts rotate the web rolls will bodily move in an arcuate spiral path.

5. In a web replenishing device, the combination of a pair of pedestals,two shafts carried one by each pedestal in axial alignment with eachother, means for rotating said shafts, a spider carried by each shafthaving arms, a shaft carried by each arm near its end having a crank onthe inner end, a chuck on each crank for supporting the end of a webroll, a gear on the other end of each last named shaft, and a gear fixedto each pedestal and meshing with a plurality of gears on said shafts-0nthe arms of the spider for controlling the rotation of the chucks on theaxes of the shafts which support them when the spiders are rotated bythe first named shaft.

6. The combination with a reel rotatable on a central axis, of means onthe reel for supporting a web roll spindle, and means for giving the webroll spindle a circular motion about an axis on the reel, as the reelrotates on its own axis.
